A truly bizarre day to announce a new notebook, Dell's Inspiron Mini 12 is officially the most gargantuan netbook on the block. I wasn't exactly blown away by it when I scoped it briefly a couple months ago, but Laptop was sufficiently impressed in its more in-depth hands on to compare it to the MacBook Air and Voodoo Envy—but you know, 0.2 inches thicker, more ports and you know, a thousand dollars cheaper at only $599.

Under the hood, it's a standard netbook kit—1.6GHz Atom (though the more energy efficient next-gen one that lets it live for up to three hours on a 3-cell battery), smallish 40, 60 or 80GB hard drive, not a whole lotta RAM—though you've got a full-sized keyboard and 1280x800 12-inch screen. Unfortunately, it's only available with Vista at launch (which, also oddly, is only in Japan initially). Since Vista historically runs like garbage on these things, holding out through the late November debut here for the XP and Ubuntu variants coming by year's end would probably be more prudent.

That said, the Mini 12 is definitely an interesting little experiment from Dell—a mutant mashup of netbook and notebook that might hit some heretofore undiscovered sweet spot, or simply look verrry attractive to some given the current economic climate. Update: Full press release below—apparently it's a Twitter machine too:
